Study Notes
Perceptual Constancies Overview
- Perceptual constancies allow humans to perceive objects consistently despite variations in retinal images (e.g., a door remains rectangular despite appearing trapezoidal when open).
- Common types include size and shape constancy.
Kaye and Bower's Study
- Investigated shape constancy in infants using a dummy and corresponding images.
- Found babies preferred the first image that matched the shape they were feeling, indicating an innate ability for shape constancy.
- Supports Gibson's theory of perceptual development.
Implications of Kaye and Bower's Findings
- Infants demonstrate a basic understanding of shape constancy.
- The study's limitations include difficulty in interpreting babies' actions and the possibility that infants were recognizing different shapes instead.
Slater, Mattock and Brown's Research
- Focused on newborns' reactions to small and large cubes.
- Found newborns gazed longer at new cubes, indicating an awareness of size constancy even when retinal images were identical.
- Suggests innate size constancy may exist but could depend on maturity and experiential context.
Evaluation of Slater, Mattock and Brown's Study
- Provides evidence for innate understanding of size constancy.
- Supports the concepts of Gibson’s theory concerning perceptual development.
- Limitations include uncertainty over whether infants' longer gazing was due to novelty rather than size perception, as babies cannot verbally communicate their reasons.
Concept of Habituation
- Refers to the process of becoming accustomed to stimuli, leading to decreased attention (e.g., consistently seeing one’s nose and ignoring it).
- A critical phenomenon in understanding perceptual adjustments and sensory awareness.
